Nice Hat / Toys

  • Too many LEGO kits to list, since the little plastic people can only be distinguished from one another by their nice hats at a quick glance.
    • However, the BIONICLE line is all about the characters striving to locate and control various Masks of Power - since all their "faces" are identical, they're literally defined by what they wear on their heads.
